To all whom it may comm:

Be it known that l, FRANK ll. l-llrnnia BRANDT, a citizen of the United States, and a resident of Saugerties, in the county of Ulster and State of New York, have invented certain new and useful dm rovements in Cutting and Coiling Crepe aper, of which the following is a specification.

My invention relates to the process and apparatus for cutting and coiling crepe pa er.

y invention is directed to apparatus and process for severing sections of crepe e roll and coiling those sections into smal rolls, a particular object being to avoid distortion of the paper during the handling and to carry out the operations rapidly.

This application constitutes a continuation of my Patent Number 1,403,246, filed December 18, 1916, granted Jan. 10, 1922 for paper rolling machine.

Other further objects and advantages of my invention will appear from the following description taken in connection with the accompanying drawings forming a part of this application in whichig. l is a side view of a machine em-= bodymg my invention and adapted to carry out my process.

Fig. 2 is a view side of Fig. 1.

Fig. 3 is a diagrammatic view of the construction shown in Fig. l, and

Fig. 4 is a view from the right hand side of Fig. 2.

Referring to the drawings it will be seen that the machine involving my invention comprises frame members, 1 and 2 suitably interconnected and braced together upon which are mounted various shafts and parts making up the machine.

Power is delivered to the machine at the pulle 3 (Fig. 2) which drives the" shaft 4. 6n this shaft is a pulley 5 which, through the belt, 6, drives the pulley 7 on shaft 8, which carries one of the cones 9 of a variable speed mechanism. The other cone 10 is carried by the shaft 11 and power is transmitted from one cone to the other by the member 12 which is shifted along the cone by the adjusting device 13. The shaft 11 carries the pulley 14 which, through a belt 15, drives the shaft 16 on which is mounted a cone 17 over which 18 runs to the cone 19, the belt being taken from the right hand shifted by an adjustable guiding device 20. The cone 19 drives the shaft 21, upon which is positioned the roller 22. Swinging freely on the shaft 21, are arms 23 which are yieldingly pressed upwardly by the spring 24 which surrounds curved guide members 25' which pass through the brackets 26 on the frame. A. roll of crepe paper 27 is supported upon a shaft 28, which rolls upon the arms 23, so that the roll of crepe paper 27 will come down into contact with the roller 22 and be driven thereby. the weight of the roll of paper decreases, it is raised by the arms 23 so that it is brought more firmly into contact with the roller 22, whereby a regular feeding is eh ected. At this point l call attention to the fact that my invention relates primarily to the hendling of crepe paper, which by reason of its lack of body and tendency to become distorted under tension must be handled with great care, and with strict avoidance of tension in every operation.

The web of paper 29 passes over a smooth roller 30 which is driven at a higher pe ripheral speed than roller 22 by the belt 31 from the pulley 32 on the'shaft 16. The web then drops down into a loop A. provided to take care of diiferences in speed of operation, to avoid tension and to per mit the paper to resume its normal state if it has been stretched. The web then passes over the rollers 33, 34 and 35 held in the guide frame 36 and thence up and over the grooved roller 37 against which it is pressed by the roller 38. llnto the grooves 39 of the roller 37 extend the fingers 40 which lift the paper from the roller and it thence drops downward. The fingers 40 are part of a doctor 41 and just below the doctor 41 is a resilient doctor 42 and below that the bed knife 43, these parts being supported on the frame. The web drops down below the bed knife to the coiling mechanism B, hereinafter more fully described. During its descent it may be guided by fixed parts or moving tapes as conditions require.

Mounted upon the main shaft 4 (Fig. 2) are two arms 44 which carry between them a fly knife 45 at one end and a connecting member 46' at the other end. Once during each revolution of the main shaft 4 the fly knife 45 cuts the web by cooperation with the bed knife 43, and the spring doctor 42 Eur llltl draws the edge of the web away from the bed knife to prevent any jamming) up of the web by reason of adherence rou ht about through the cutting operation. he

length of the stri s into which the web is severed is control ed by val ing the s eed of the roller 32 by means of t e' cone pu leys 9 and 10 and the adjustable transmitting member 12. The end ofthe webbing comes downwardly until it contacts the series of interposed rollers 46, 47, 48, 49 and 50. These interposed rollers comprise shafts 51 on which are disks or rollers 52, the rollers on one shaft being interspaced with the rollers on the adjacent shaft. The main shaft 4 carries a large gear 51', which meshes with the gear 52 on the shaft of which is the gear 53, which meshes with the car 54, which drives the gear 55, on the siaft of which is a gear 56 which drives the train of gears 81 which rotate the interposed rollers 46 to 50, and the train of gears 81. (See Fig. 1.) Shaft 71 pa$es through and supports one end of bars 80 which extend to the frame and support the shafts of rollers I 46, 47, 48, 49. The upper surfaces of the interposed rollers are all moving to the right in Fig. 1 and-carry the loose end of the web in that direction to be coiled. The coiling means is as follows:

Swinging loosely upon the shaft 57 which carries the gears 52 and 53 are two arms 58 connected together vby the rod 59. On the shaft 57 there are mounted rollers 60 over which run tapes 61 to the rollers 62 which run loosely on the rod 59. (See Fig. 2.) These rollers 62 are interspaced between the rollers 50 and are in line with the rollers 49. The web is thus carried to the right until it strikes the tapes 61 when the end is raised and carried upward. If the end does not fall back upon the-following portion of the web to startthe coil it goes upwardly until it strikes the rollers 63 and 64, the rollers 63 being interspaced between the rollers 60 (see Fig. 2) and the rollers 64 being interspaced between the rollers 63. These rollers are driven by a train of gears 57 from the gear 52 on the shaft 57, as best shown in Fig. 1. The lower surfaces of the rollers 63 and 64 are moving to the left and when the edge of the web strikes them it will be turned back upon itself and as the web is fed along a coreless roll will be formed upon the rollers 46 to 50.

Referring now to Fig. 2 it will be seen that plates 65 are so positioned that the web in dropping from between the rollers 37 and 38 will fall between them. In order that the ends of the coil may be even these plates are constantly brought together and spread apart to jog the roll into shape.

These joggers are mounted upon slides 66 which move in guides 67 and are actuated by connecting-links 68 connected to crank arms 69 n be shafts 70 wh h are driven from bevelled gears on the shaft 71 which carries the gear 55. Y

The web accumulates in a coil upon the rollers 46 to 50, in lengths, varying accordm to the s d of the movement of the roIler 37 an after the web is severed the roll is to be discharged uponthe conveyor 75 as follows: The two arms 58 and the ta es carried thereby running over the ro ers 60 and 62 constitute a guide to hold the coil upon the rollers; 46 to 50. The upper end of one of the arms 58 carries a roller 76 (see Figs. 1 and 2) which rests against a cam 77 which is mounted on a shaft 78 which carries a gear 79 meshing with the gear 80 on the main shaft 4. The roller 76 is held against the cam 77 by the spring 84' and each time the flat ortion 7 7' of the cam comes under the ro ler 76 the spring swings the lower end of the arms 58 to the right and the coil is carried out by the rollers 46 to 50, and dropped upon the conveyor 75.

It will be seen from the foregoing oon-' struction that I have provided a ainst distorting the crepe paper during t e feeding and that inasmuch as it is coiled while it lies freely no tension is imparted to it during that operation. It will also be seen that the ends of the coil will be even and that the coil is discharged when completed.

While I have described my invention in considerable detail I do-not wish to be limited to the constructional features described, but intend that the mechanism described shall be considered as exemplifying devices embodying my invention and carrying out my process.
